Yikes, there’s was a UK music group of the early nineties called “Sabres of Paradise” I imagine this book was the inspiration for their name.

Although I don’t think their music reflects any of this.

Man’s inhumanity is something terrible to behold in figures like this.

- Holocaust (שּׁוֹאָה) 5.5M-6.2M Jews, 200k-2.2M Romani, 5k-100k LGBT, 10k-35k political

Would the LGBT and political prisoner figures be sub-sets of Jews/Romanis? Or would they be in addition to those figures?

I have read before about specific symbols used in the camps to identify LGBT people, but would the person murdered in a camp who was both Romani and gay be counted once or twice in those figures?

Indeed, not comprehensive:

- Mao Zedong's Great Leap Forward 35M-45M

- Mao Zedong's Great Proletarian Cultural Revolution - 3M-10M

- Joseph Stalin's collectivisation 5M-7M

- Joseph Stalin's Holodomor 5M+

- Joseph Stalin's Goloshchekin genocide (Kazakhstan) - 1.3M-1.75M

- Pol Pot's Khmer Rouge - 1.3M-3M

- Islamic (Mughal) invasion(s) of India - 100M+

- Mongol conquests - 30M+

There are of course many more. Did you use Wikipedia to get that list?
